17-year cicada broods make their presence known in New Jersey Special

As the unusual cold snap broke on Sunday, the 17-year cicadas made their appearance known - emerging from the ground in swelling numbers.

The unusually wet and chilly weather that has enveloped New Jersey for the first half of the Memorial Day weekend has kept a very large number of the state's residents from emerging more vociferously to enjoy the sun's many offerings.
And the human populations stayed inside as well.
However, Sunday offered a return to more seasonal temperatures - and with that return came a more populous spectacle, as thousands of 17-year cicadas, also known as the periodical cicadas, made the beginnings of their presence known.
While their numbers appeared to have been muted due to the undesirable weather conditions, (CFACT.org offers a humorous post on the cicadas appetite for warmer temperatures), the 17-year periodical cicadas have begun making their slow climbs through grass stalks and up tree limbs - transforming from a blind root-nibbling underworld grub to one of the loudest and most poetic crooners in nature.
In the coming weeks, it is expected that their numbers will total in the billions - and many leafy areas of New Jersey are expected to see magnificent waves of the red-eyed 17-year brood.
And just as quickly as they pay us this astonishing and alien visit, the lucky among them will sing and mate and die - and we will have to wait another 17 years to experience them again.
